Hello! You asked me on my COTMLOTH video to check out yours and give some feedback! I think you have a really strong concept here! I really like what you did with it. My suggestion is to study a lot of still life. Take things from real life and study from it ex drapery for the cloaks, anatomy(the human body is one of the hardest things to draw!) and take ideas from landscapes and sceneries for your backgrounds! Keep up the great work!
